Done Being Her Secret

Luna has been married to Alberto, a film actor, for years, and they have a son, Albito. Nobody outside the marriage knows. Alberto agreed to go on the dating show Encuentro de Amor with Luna's younger sister Marta to help her find someone, on one condition: Luna makes the marriage public and lets him be her husband in front of people. Luna refused, saying Marta would be crushed by the press once the connection came out. Luna has kept her mother's dying instruction since childhood, which was to look after Marta, and she has done it the way a servant does. She went onto the show herself as an ordinary contestant, there to make Marta look good and get her matched. Marta read it differently and became convinced the actor was interested in her.
